rtc: zynqmp: Fix optional clock name property

Clock description in DT binding introduced by commit f69060c14431
("dt-bindings: rtc: zynqmp: Add clock information") is talking about "rtc"
clock name but driver is checking "rtc_clk" name instead.
Because clock is optional property likely in was never handled properly by
the driver.
